Ginrai, also known as Jinrai Hazuki, is one of the central characters in the anime Shin Hakkenden, distinguished as a member of the group of eight warriors. His background is deeply marked by a tragic family history. He is the estranged brother of another warrior, Noboru, having been kidnapped from his family as an infant. This early separation set him on a lifelong path defined by a longing for connection. His primary motivation throughout the story is a deeply personal search for his long-lost parents, hoping to reunite with them and uncover the truth of his origins, unaware that they have been deceased for a significant time.

This personal quest heavily influences his role within the larger narrative and his key relationships, most notably with Noboru. Instead of a warm sibling bond, their connection is characterized by tension and grief, as Noboru holds Ginrai responsible for the deaths of their parents, creating a significant obstacle to any potential reconciliation. This conflict suggests a personality that is likely resilient, driven, and accustomed to adversity, carrying the weight of a false accusation and a stolen past while still pursuing his goal. His character development revolves around the painful irony of his search, as he strives for a reunion that is impossible, forcing him to eventually confront the truth about his family and redefine his identity beyond being a lost child.

As one of the eight warriors, Ginrai possesses a notable ability tied to his role. His power is derived from his specific jewel, which is called the "tree" jewel, representing a unique source of strength that distinguishes him within the group. Like the other warriors, this jewel is a power crystal that serves as the foundation for his combat capabilities and his role in the team's collective mission.
